" `4 claims. (o1. 10s-422) The `invention relates vto floors more particularly designed for use in railway' freight'cars and has for its object theobtaining of a more'durable construction and one having Various other 5 advantages. To this end tlielinventionconsists yin the construction as'hereinafter set forth. In the drawing:

Figure 1 vis a longitudinal section through a f sary to provide for nailing downfthe blocking for holding the lading from shifting, this metal facing plate is apertured'or slotted to permit the driving ofnails into the Wooden licor therebeneath. Av serious objection to such construction is that with certain types of lading, such for u .instance as material held in paper or cle-th sacks, the uneven surface formed by the apertures in the plate will do injury. To overcome this defeetV I have designed a construction which still retainsv the metallic facing 'apertured for the passage of nails, but vwhichprovides an unbroken upper surface forsupp'ort ofthe load. This is preferably accomplished' by the'fllling 'of the material having its upper surface flush with the upper surface of the impervious This will' still permit of driving the nails, but when these are withdrawn theplastic nature of the material will soon heal the breach.

My improved construction .may be applied either to the entire car floor or' only to a part thereof. Wherer applied to the entire floor, it is possible to constructuth'e Wooden lportion of thinner material. than that generallyk used and to still retain the same strength, by reason of themetallic reinforcement. As shown in Figure l, Aare the match lwooden floor boards, and B the metal facing platescovering the saine. The plates B m. are provided with a series of apertures C suitably spaced for convenience in the nailing of the blocking. These 'apertures C n are all lled with a mastic or other' plastic compound D of ysuch a apertures in the metal facing plate with a plastic n said sheathing and `presentingan unbroken will permit of driving a nail therethrough. Also, when the nail is withdrawn the displaced material will flowfback to close the opening. Various plastics may be used for this purpose, ybut I have found a suitable material to be that commercially know as #5 red caulking cement put out by the Continental Works Company of Chicago, Illinois.

As shown in Figure `2, the metallic facingB is laid directly in contact with the floor boards A and the plastic material D is used only to ll the apertures C. In Figure 3, theplastic imaterial extends over the whole surface ofthe wooden floor, as indicatedat E, the facing plate A being laid thereon and with plastic/material D filling the apertures. iIn Figure 4, the plastic material not onlyy extends under the facing plate as at E, but also over the same as at F, as Well as lling the apertures -C. In each of these constructions the top surface is level and forms a support for the load, and also lin each, nailing of theblocking is permitted, while the openings formed when the nails are Withdrawn are healed by theplastic material.

What I claim as my invention is:

l. A car flooring comprising a Woodeny underloor, a metallic sheathing coveringthe upper face of saidwooden floorprovided withy a plurality of apertures of sufficient size for convenient insertion of laden securing means, thereby leaving open areas into which certaintypes of laden may enter to the injury thereof when dragged over the floor, anda penetrable. plastic material filling the apertures in said sheathing.

2A car flooring comprising a Wooden underfloor, a metallic sheathing covering the upper face of said' woodenfloor provided with` a pluralityl of apertures of suflicient size for convenient insertion of laden securing means, rthereby leaving open areas into which certain types of laden may enter to the injury thereof when dragged over the floor, and a penetrable self# healing plastic material filling theapertures in said sheathing. f

3. A car flooring comprising a Wooden underrloor, a metallic, sheathing covering the upper face of said Wooden floor provided with a plurality of apertures of sufficient size forI convenient insertion of laden securing means, thereby leaving open areas into which certain types of laden may enter vto Vthe injurythereof when dragged over the floor, and a penetrable. selfhealing plastic material llin'gthe apertures in surface for supporting the lading.r

4. A car ooring comprising a Wooden underfloor, a metallic sheathing covering the upper face of said wooden oor and provided witha plurality of apertures of sucent size for convenient insertion of laden securing means thereby leaving open areas into which certain types of laden may enter to the injury thereof when dragged over the oor, and a penetrable plastic material covering the surface of said underoor and extending upward into the apertures in said sheathing.
